We've looked at this too... but you need not necessarily dump them at the last second to make a difference. Dump them with 10 or 15 seconds left in the match, or how ever long it takes to get back to the ramp... the other team still needs to reenter those balls into the field and enough to make a difference would take a few seconds to do, and a few seconds to either shoot or dump and they won't get back to the ramp. So yeah, I think it can be done, and if use properly, quite effective.
